Pool Grotto

Jutting from the southwest of the Pool, this naturalistic boulder grotto is the well-concealed reminder that Central Park is entirely man-made. Behind the boulder, a 48-inch pipe feeds the Pool fresh water from the Reservoir just half a mile south. The conduit is actually the main source of water that also keeps the Loch, the cascades in the Ravine, and the Harlem Meer filled and flowing.
